For poset P with the least element 0, the zero divisor graph of P, denoted by Г(P), is an undirected graph with vertex set Z(P) and, for two distinct vertices x and y, x is adjacent to y in Г(P) if and only if fx; yg` = f0g. In this paper, we study the planar and outerplanar indices of Г(P) and completely investigate these indices of Г(P) when Atom(P) is nite. |
